Now that I'm hooked on being an aquarist, I went ahead and set up a 10 gallon tank I had in my garage from when I had an Iguna. I'm doing it right this time, fishless. By using the article on this website, I'm putting in a few flakes of food every 12 hours. My question is: what is a few? I've been dropping in about three (3). Is there any particular food I should use? Right now, I'm using Tetra Crisps. I started this on Saturday and don't have any test readings yet. Also, should water changes and vacuuming be done during the initial cycle?
